The Silk Road stretched more than 7,000 kilometers at its zenith, and was used heavily from the second century BC to the 16th century.

The Silk Road has finally become a World Heritage Site, 22 of the 33 sites are located in China.

"It turns a new page in terms of World Heritage Sites because our previous items on the list are individual spots rather than a continuous line," said Tong Mingkang, the deputy director of China's State Administration of Cultural Heritage and the head of China's delegation to Doha.

There are 33 historical sites within the project, and 22 of them are in Chinese provinces-Shaanxi, Henan and Gansu, and the autonomous region of Xinjiang Uygur. Eight of these sites are in Kazakhstan, and three are in Kyrgyztan.

"A detailed plan for protection and improvement of surrounding areas was made for each spot, making this application much more complicated than previous ones," said Tong. "The success also gave us important experience in terms of cross-border cooperation in the field."

He also said that China will most likely submit more requests for World Heritage status in the future.

The United Nations Educational, Scientific and Cultural Organization began encouraging countries located along the Silk Road to cooperate in bids for World Heritage status in the early 1990s, but this work began only in 2006 because of academic disputes over where the path should be outlined.
